520			\|a Coenzyme Q (CoQ) was an electron carrier within the mitochondrial respiratory chain, serves as a cofactor for various mitochondrial dehydrogenases thereby playing a significant role in plant growth and development. In this study, GhCoQ9 was identified through transcriptomic analysis of cotton under salt stress. GhCoQ9 participates in the synthesis of coenzyme Q. Under salt stress condition, cotton plants with GhCoQ9 silenced exhibited more pronounced growth inhibition compared to the control group. Additionally, the catalase (CAT) and superoxide dismutase (SOD) levels were significantly increased, while the level of malondialdehyde (MDA) showed an upward trend. Microscopic analysis of cotton leaves revealed that under salt stress conditions GhCoQ9 -silenced plants exhibited reduced stomatal aperture, cellular destruction, cell shrinkage and deformation, and increased intercellular space compared to the control plants. The ultrastructure of GhCoQ9-silenced plants exhibited increased susceptibility to salt stress, primarily manifested as damage to the chloroplast and mitochondrial structures. We also investigated the function of CoQ9 in Arabidopsis, the results showed that coq9 mutant exhibited reduced germination rate and significant inhibited growth under salt stress. These findings suggest that GhCoQ9 plays a crucial role in the adaptation of cotton to salt stress by preserving the integrity of chloroplast and mitochondrial structures
